چکیده انگلیسی
Microalgae have a potential to serve as a renewable feedstock for synthesis of biodiesel, rich in saturated and unsaturated fatty acids and valuable biomolecules. Role of several parameters such as nutrient composition, light intensity, photoperiod and pH on growth and lipid productivity was investigated. A freshwater green microalga Scenedesmus abundans was selected as a potential candidate for production of biodiesel and its growth conditions were optimized for enhanced lipid accumulation. The lipid content of the strain has been increased up to about 48% when grown in modified Fogg's medium at pH 8 with light intensity of 40.5 μmol mâ2 sâ1 and photoperiod of 16 h light:8 h dark. Lipids were transesterified and the fatty acid methyl esters (FAME) thus obtained were analyzed by GC-MS. They possess more than 80% of C16 to C18 fatty acids, which are major precursors for biodiesel production. The FAME consisted of saturated (47.83%), monounsaturated (26.38%) and polyunsaturated (25.20%) fatty acids. Several important biodiesel quality parameters were predicted and compared to the corresponding specifications in the American and European biodiesel standards. The study opens up new vistas for utilization of the microalga, S. abundans for efficient production of biodiesel.
